Estimating statistical distributions using an integral identity
Cheng Zhang, Jianpeng Ma
We present an identity for an unbiased estimate of a general statistical distribution. The identity computes the distribution density from dividing a histogram sum over a local win…

Enhanced sampling in generalized ensemble with large gap of sampling parameter: case study in temperature space random walk
Cheng Zhang, Jianpeng Ma
We present an efficient sampling method for computing a partition function and accelerating configuration sampling. The method performs a random walk in the space, with bei…
